How to observe a total solar eclipse without hurting your eyes, how to see a solar eclipse without h

End the basin of water Look at the reflection in the water.

1. Look with a filter. The material used to make the filter can be waste film, or it can be made from a broken computer floppy disk core.

2. Look at it with black glass. Candles are used to blacken pieces of glass, which can be used to watch a solar eclipse.

3. Look at it with a basin. Drop an appropriate amount of ink in a basin of water, make black water, and watch the eclipse through the reflection of the sun.

4. Small hole imaging. Using two boards, dig a small hole in one of the boards and let sunlight shine through the hole onto the other board.

5. Shade observation method. During a solar eclipse, the gaps in the shade of the trees will become natural holes, and the small bright spots under the shade of the trees are all images of the sun's holes.

6. Look with eclipse glasses. There are special eclipse glasses** on the market.

7. Look with a camera. Be careful, be sure to have a filter, viewing the eclipse directly from the frame can also hurt the eyes, never try it. It's best to use a tripod when shooting, and if you want to get a clear image of the eclipse, you also need a telephoto lens.

This is because during the total solar eclipse, the overall environment becomes darker, relatively, the ultraviolet and infrared rays of the sun will become stronger, because the human eye tends to glow objects, it is easy to attract people's eyes, when observing the total solar eclipse, you should choose a sunny area as much as possible, and pay attention to the safety of the eyes. Because sunlight is a million times stronger than moonlight, it cannot be directly ** with the naked eye or through a telescope without light-reducing equipment, otherwise it is easy to cause retinal damage and even blindness.

No. When observing a solar eclipse, it is important not to use the naked eye directly** to avoid strong sunlight burning the eyes, causing solar ophthalmia and solar eclipsal retinopathy, and in severe cases, it can cause permanent visual damage, even if it is a partial solar eclipse, it cannot be directly observed with the naked eye. <

Eclipse observation method

1. Small hole imaging observation method: Aperture imaging allows sunlight to pass through a small hole, put a white screen 1 meter away behind the aperture, and let the sunlight beam shine on the white screen through the aperture, projecting an image of the sun. This projection observation method can be taken from local materials.

For example, a board with many holes, a loose and broken straw hat, or even the fingers of both hands can be crossed to project a series of images of the sun on the screen.

2. Telescope projection observation method: You can prop the binoculars on a tripod and put a whiteboard on the back to project a magnified image of the sun. Never hold a telescope directly to the sun, if you use a telescope to look directly at the sun, be sure to use a filter.

3. Goggle observation method: The most common goggles are the welder's goggles with a shading number of 14, which can be purchased in the welding equipment market.

4. Bard membrane observation method: Bard film is a metal-coated resin film that can be used for visual and photographic purposes. It is very thin, the optical quality is excellent, and the Bard film that can be bought today is available in two densities, one for visual use and one for photographing).

5. Observation of solar eclipse glasses: There are many special observation glasses for solar eclipses on the market**, and you must pay attention to the selection of observation glasses when buying.

The reason why a total solar eclipse hurts the eyes, the sunlight is too strong, it will damage the macula of the eyes, and this damage is irreversible.

During a solar eclipse, we will always stare at the sun, but usually not, the key is to look at the length of the sun. Even in normal times, staring at the sun for a few minutes will impair. During a solar eclipse, there will be a light drop, which is illuminated by strong light for a period of time, that is, the ultraviolet rays are higher than normal, and high-intensity ultraviolet rays can blind people.
